Titel:
Deep Q-Network Updats for the Full Action-Space Utilizing Synthetic Experiences

Autoren:
Wenzel Pilar von Pilchau, David Pätzel, Anthony Stein, Jörg Hähner

Venue:
2023 International Joint Conference on Neural Networks

Abstract:
Deep-Q-Networks are built in a way that, given a state, they predict the Q-values for the entire action-space. However, given an experience, the training update only incorporates the loss value for a single action—the one that has actually been executed. This is due to the rewards and follow-up states (required for computing the loss via the temporal-difference error) associated with the other actions being unknown. With these missing values at hand, or at least estimates of them, an update over the entire action-space would be possible. We present the Full-Update-DQN which is able to do just that. Sub-losses are weighted to compensate for uncertainty and noise and we are able to show in four different experiments in sparse reward settings, that our approach is able to solve these problems more consistently and even faster than the original approach.
